They almost always leaked and even Ford manuals warned mechanics not to tighten fan belts too tight. The excess slack allowed belts to slip and lose contact with the generator and water pump pulleys, causing more cooling and power problems. Speedway's completely new water pumps feature severe-duty roller and ball bearings, close tolerances and modular impellers to provide maximum flow and reduce cavitation. They also have modern ceramic seals on a heavy duty 5/8" shaft, making the assembly exceptionally strong and more efficient. All mounting areas are spot faced for improved fit and sealing.

Part # 91603023 Reviews Yes Rated by Ike on January 20, 2022 Summary: I bought this pair this week .and just installed them. They look and feel great...but when i installed the driver side i had to grind away casting material around the upper left bolt hole to allow the pump to seat against the block.The passenger side was much thinner in this area and seated fine. Just a heads up. Yes, I recommend this product. Great Product Rated by Dirtdigger on September 12, 2021 Summary: good fitment Yes, I recommend this product. I would purchase this again.
